Model Context Protocol, or MCP, is one of the most exciting things happening in developer tools right now. If you want to maximise the benefits of AI in your workflow, now is the ideal time to start exploring it. There is a significant amount of new work happening in this space, and developers from diverse backgrounds are beginning to adopt it.
But figuring out which MCP servers are worth your time can be tricky.
I have compiled a list of MCP servers that every developer should be aware of.
1. Rube MCP: Universal MCP server for all your apps
When you start using MCP servers, the first hurdle is setup. Each server, like GitHub, Slack, Supabase, Postman, and so on, needs its own configuration. That’s fine for one or two, but once you want to combine several, it becomes a time sink.
Rube takes care of that. It’s like a central hub where you can run and manage all your MCP servers together. Instead of repeating the same steps for every tool, you set things up once and use them across multiple AI clients like Cursor, Claude, or VS Code.
How developers use it:
Quick setup: connect your apps once and reuse them everywhere
Works across clients: keep the same servers active in Cursor, Claude, or VS Code without reconfiguring
Chain tasks across tools: fetch records from Linear/Jira, email them with Gmail, and post the results on Slack, all in one flow
Share with your team: give teammates access to the same integrations through a single link.
Built-in OAuth: It handles app authentication, so you can focus on getting things done.
Stay secure: Rube is built on Composio, which handles encryption and safe logins.
The value is that you spend less time setting things up and more time using MCP servers for real work. Rube streamlines the complex part of managing servers into a seamless background process.
Figma MCP: Design to code without coding
Design files are often where developers lose time. Developers rely on it for layouts, assets, and style guides; however, extracting the correct details from a design file can be a time-consuming process. You should scroll through layers to find a component or ping a designer to confirm spacing. These minor interruptions add up during a sprint.
Figma MCP streamlines the process by allowing you to access design details directly through AI. No waiting on exports or digging through files, the information comes when you ask for it.
What you can do with it:
Access assets: pull icons, images, or components from a file in seconds
Check styles: confirm spacing, colors, and typography without manual digging
Review changes: see what’s different in the latest design update before writing code
Generate snippets: turn design tokens into CSS or components you can use directly
Stay aligned: reduce back-and-forth and keep handoff clear between design and development
The result is faster implementation and fewer blockers. Developers stay focused on building features, and designers spend less time fielding small requests.
Context7 MCP: Up-to-date docs for any developer tools
Every developer has faced the frustration of missing context. You open an AI tool expecting a clear answer, but the response feels incomplete because it doesn’t have the right background. Documentation is scattered, code references are buried, and decisions are locked away in chat history. Without the right context, even simple tasks take longer than they should.
Context7 MCP focuses on solving this problem. It gives AI direct access to the information that matters so responses are grounded and accurate. That means when you ask for something, the assistant can pull in the right background from your project and deliver results you can rely on.
Where it adds value:
Provide accurate context: connect AI with the right background before it answers
Reduce noise: filter out irrelevant data and surface only what’s useful
Support RAG workflows: power retrieval-augmented generation for stronger results
Stay current: draw from the latest project data rather than outdated notes
Unify teams: give everyone the same reliable context across tools
The result is less time chasing information and more confidence in the answers you get. Context7 MCP makes AI a dependable partner for development work, not another source of distraction.
GitHub MCP: Work with GitHub remotely from IDEs
GitHub is the home base for most developers. It’s where code is stored, where pull requests get reviewed, and where issues are tracked. If you’re building software today, you likely spend a significant portion of your day here.
That also means you know the little pain points. Stopping mid-code to create a bug report. Clicking through the UI to check if a pull request passed tests. Searching for the latest commit or figuring out which PR needs your review. These aren’t hard tasks, but they break your flow and add up over time.
GitHub MCP helps cut through that. By connecting GitHub with AI, you can handle those actions quickly, without leaving your workflow.
Here’s what it can do for you:
Create issues instantly by simply asking the assistant, instead of stopping your work to open GitHub.
Check pull request status and see if tests have passed without digging through the UI.
Fetch the latest commits on any branch while staying in your coding environment.
Summarize open PRs so you know what needs attention right away.
Assign or update issues for your team without context switching.
For developers, this means fewer interruptions and more time focused on actual coding. For teams, it makes staying on top of updates easier and keeps work moving smoothly.
Playwright MCP: Automate testing and web
Testing is a part of development that no one can skip, yet it often feels like it slows everything down. Setting up end-to-end tests, debugging failures, and checking coverage can eat up hours that you’d rather spend building features. Even with tools like Playwright, running tests often means leaving your flow to switch into another environment.
Playwright MCP brings testing closer to where developers actually work. Linking Playwright with AI makes writing, running, and analysing tests much more straightforward. Instead of setting everything up manually, you can ask for the tests you need or run existing ones directly through the assistant.
Practical actions it supports:
Run browser tests: execute end-to-end tests on demand without leaving your workflow.
Debug failures: get clear explanations of why a test failed and how to fix it
Generate new tests: create test cases for features or edge cases automatically.
Check coverage: see where your current suite leaves gaps that need attention
Streamline QA: integrate testing into daily work instead of treating it as an afterthought.
The result is more reliable code with less hassle. Developers catch problems earlier, QA teams get stronger coverage, and projects move forward with confidence. Playwright MCP turns testing into a natural part of development rather than a roadblock.
Linear MCP: Fetch, edit and complete tasks remotely
Every developer knows the struggle of keeping tasks updated. A bug pops up, but you forget to create a ticket. Priorities shift, and suddenly half the board feels outdated. Someone asks about progress, and you’re digging through issues to piece together an answer. The work of managing the work can start to feel heavier than the coding itself.
This is where Linear MCP steps in. By tying Linear into your AI assistant, the routine updates stop being interruptions. You can log a bug the moment you notice it, check the status of open issues without leaving your editor, or even get a quick snapshot of sprint progress while staying focused on your code.
With Linear MCP, you can:
Create tasks: log bugs or feature requests right as they come up
Update issues: change status, assign teammates, or adjust priorities in seconds
Check progress: get a quick summary of open tasks or sprint status
Spot blockers: see which tasks are holding others back before they become problems
Stay organized: keep the backlog clean and priorities clear without extra effort
The result is less time spent managing boards and more time moving projects forward. Developers can stay focused on building, while teams get a clearer view of what’s happening without relying on constant status meetings.
21st.dev MCP: Make your LLM build beautiful components
Getting code into production is about more than just writing it. Teams need to track progress, manage releases, and make sure nothing slips through the cracks.
21st.dev MCP brings more clarity to that process. It connects development workflows with AI so teams can see progress, release readiness, and velocity without extra reporting overhead. Instead of spending hours compiling updates, you can get a clear picture of project health in just a few seconds.
What it lets you do:
Track releases: monitor what’s ready to ship and what still needs work
Measure velocity: understand how fast your team is moving and spot slowdowns early
Check dependencies: see what tasks or features are blocking progress
Generate insights: create summaries of workload and project health instantly
Stay aligned: keep both developers and managers up to date without manual reporting
The value is simple: developers spend more time coding, and teams get the visibility they need without adding more meetings or dashboards. 21st.dev MCP makes release management feel lighter and keeps projects moving toward production.
Supabase MCP: Automate working with
Every project needs a database, but working with one often feels like a distraction from building features. You might need to write a quick query, add a column, or check permissions, and suddenly you’re bouncing between consoles, docs, and your editor. It’s not hard work, but it does break momentum.
Composio offers managed auth for Supabase, so you can permission who can actually access and what.
Key things you can do with Supabase MCP:
Run queries: fetch, filter, and test data without juggling consoles
Manage tables: create, modify, or drop tables and columns on the fly
Check authentication: view or adjust user roles and permissions in seconds
Trigger functions: call backend functions whenever you need to validate behavior
Explore schema: see the structure of your database at a glance
By simplifying database work, Supabase MCP makes backend tasks less of a roadblock. Developers can move from idea to implementation faster, without losing time to setup and maintenance.
Slack MCP: Send message, get updates, and sumarise chats
Every team relies on Slack, but for developers, it often feels like both a lifeline and a distraction. One moment you’re checking a quick update, and the next you’re pulled into endless threads, side conversations, and notifications. Important context, like a decision about a feature or a bug report, gets buried under gifs and casual chatter. By the time you find what you’re looking for, you’ve already lost focus on your work.
Slack MCP changes how you interact with all that information. It connects Slack to AI, so the flood of messages becomes something you can manage. Instead of wading through channels, you can ask for the key points, the decisions that were made, or the messages that matter to you.
Practical actions it supports:
Summarize threads: turn long discussions into clear takeaways you can read in seconds
Highlight decisions: surface agreements, next steps, and blockers so nothing is missed
Post updates: create reminders or share quick updates directly through the assistant
Track mentions: follow specific channels or keywords to stay in the loop
Stay focused: get the context you need without being pulled into every notification
The benefit is clearer communication and less wasted time. Developers avoid losing hours to endless scrolling, while teams make sure updates and decisions never get overlooked.
Jira MCP: Automate solving tickets from IDEs
Jira is a staple for many engineering teams, especially in larger organizations. It’s powerful, but it can also feel heavy. Creating tickets takes time, updating them often feels like busywork, and keeping track of sprint progress can quickly become overwhelming. Developers sometimes spend more time managing Jira than moving actual work forward.
Jira MCP lightens that load. Connecting Jira with AI makes everyday project tracking faster and less disruptive. Instead of stopping to fill in forms or click through dashboards, you can handle tasks with a quick request and keep your focus on building.
Where it adds value:
Create tickets: log bugs, feature requests, or tasks as soon as they come up
Update issues: change status, assign teammates, or adjust timelines on the fly
Check sprint progress: get summaries of what’s open, what’s blocked, and what’s done
Generate reports: pull a clear overview of workload or project health for your team
Stay on track: keep boards current without hours of manual updates
For developers, this eliminates the tedious task of navigating Jira’s interface. For teams, it means tickets stay accurate, sprints stay clear, and project updates become easier to share. Jira MCP transforms Jira from a cumbersome tracker into a tool that supports the workflow quietly.
Postman MCP: Interact with APIs
APIs are at the center of almost every modern application. Whether you’re fetching data, sending requests, or debugging endpoints, chances are you spend a lot of time in Postman. The problem is that managing APIs often means constant context switching, running tests in one place, checking logs in another, and keeping track of collections separately.
Postman MCP brings that workflow into one place with AI. You can interact with your APIs through natural language, making it easier to test, monitor, and debug without juggling multiple tools.
How you can use it:
Send requests: call endpoints directly and see responses right away
Run test suites: execute saved collections and confirm results on demand
Inspect responses: get clear explanations of status codes, errors, or payloads
Generate new requests: create endpoint tests for new features quickly
Organize collections: keep your API documentation and test sets structured with less manual work
The outcome is smoother API development. Developers can spot issues earlier, QA teams get stronger testing coverage, and projects move forward without waiting on manual checks.
Containers are everywhere in modern development. They make it possible to run apps consistently across environments, but managing them isn’t always smooth. Starting, stopping, and monitoring containers often means bouncing between terminal commands and dashboards. When deadlines are tight, even simple environmental issues can block progress.
Docker MCP brings container management closer to your daily workflow. It connects Docker with AI, allowing you to control and monitor containers without interrupting your current task.
Practical use cases:
Start and stop containers: spin up environments or shut them down with a quick request
Check status: see which containers are running and view their health instantly
Monitor resources: track CPU, memory, and usage patterns in real time
Manage images: pull, tag, or remove images without digging through commands
Debug environments: surface logs quickly to spot problems before they slow you down
Developers can keep environments running smoothly, and teams avoid losing time to setup and troubleshooting. Docker MCP makes containers feel like part of the workflow, not a separate task to manage.
LangSmith MCP: Automate agent monitoring
As more teams build with AI, the biggest challenge isn’t just writing prompts, it’s making sure the outputs are reliable. Developers require methods to test, debug, and monitor AI models to ensure they behave as expected in real-world projects. Without the right tools, this means lots of trial and error and very little visibility into why a model succeeds or fails.
LangSmith MCP gives developers a way to bring that process under control. It connects AI assistants directly to evaluation, logging, and testing workflows so you can see what’s happening under the hood and improve your models continuously.
What it unlocks:
Run evaluations: test model outputs against benchmarks or specific criteria
Log interactions: capture real usage data for debugging and iteration
Trace executions: see step-by-step how prompts and responses are handled
Compare outputs: check how different models or prompts perform side by side
Monitor performance: track quality over time and catch regressions early
The value is confidence. Instead of shipping AI features blind, developers can validate, measure, and improve them with the same rigour as any other part of the stack. LangSmith MCP makes AI development more predictable and production-ready.
Key takeaway
MCP has already proven itself as a powerful way to connect developers with the tools they use every day. It eliminates the friction of managing code, tasks, design files, databases, and even testing by allowing AI to handle the busywork. The servers we examined demonstrate the breadth of possibilities, ranging from GitHub and Linear to Playwright and LangSmith. MCP is shaping a workflow that reduces the burden of context switching.
The real takeaway is that MCP isn’t just a convenience. It’s becoming part of the foundation for modern development. The more teams adopt it, the more natural it will feel to let AI manage repetitive actions while developers focus on solving problems and shipping products.
